TYPOGRAPHICAL IVIACI-IINE.

Application filed March 6, 1913.

To all whom it may concern:

Be it known that I, PHILIP T. Donors, a citizen of the United States, residin' at New York city, in the county of New ork and State of New York, have invented certain new and useful Improvements in Typographical Machines, of which the following is a specification, reference being had there in to the accompanying drawing.

My invention relates to typographical machines, such as linotype machines of the general organization represented in Letters Patent of the United States, No. 36,532, to O. Mergenthaler, wherein circulating matrices are released from a magazine in the order in which their characters are to appear in print and then assembled in line, the composed line transferred to the face of a mold, the mold filled with molten metal to form a slug or linotype against the matrices which produce the type characters thereon, and the matrices thereafter returned through a distributing mechanism to the magazine from which they started. More particularly, it has reference to the parts which receive the matrices from the distributing mechanism, and its general object is to adapt such parts to receive and. handle matrices of different thicknesses with certainty and accuracy. In machines of this kind, the matrices ordinarily pass from the distributing mechanism into and through a partitioned entrance, which in turn delivers them to the magazine, and to this end the magazine and entrance are caused to register in such manner that their corre' sponding channels are practically continuous. However, the matrices are of varying thicknesses, depending both on the characters represented thereby and on the different styles or fonts in use, ranging from a very thin one containing a punctuation mark, to a very thick one representing a head letter. As the successively employed fonts may thus contain matrices of widely different thicknesses, it has been customary to vary the relative width of the entrance channels to correspond, and this result has generally been secured by bending certain of the channel partitions, when the font is changed.

It is the purpose of my present invention to obviate this necessity and to provide the entrance with guiding means adapted to Specification of Letters Patent.

engage the ears of all matrices, whether thick or thin, and consequently to guide them into correct relation to the magazine. To this end, I preferably form the entrance with grooves adapted to receive the ears of the matrices, which grooves specifically extend entirely through the entrance and reg ister with corresponding grooves formed in the magazine.

In the accompanying drawing, I have shown my invention in preferred form and by way of example, and as applied to a linotype machine, but obviously many variations and. alterations may be made therein, and further it may be adapted to other forms of typographical machines, such as typesetters, typecasters, and the like, (in other words, to handle type, dies, etc), without departure from its spirit. Generally speaking, I desire it to be understood that I do not limit myself to any specific form or embodiment, except in so far as such limitations are specified in the claims.

Referring to the drawing: Figure 1 is a transverse vertical section through the distributing mechanism, magazine entrance, and the upper end of the magazine; Fig. 2 is a sectional view, taken substantially on the line 22 in Fig. 1; Fig. 3 is a section taken substantially on the line 38 in Fig. 1; and Fig. 4- is a section taken substantially on the line 4-4: in 1.

The matrices X are conveyed along the distributer rail A by the screws B and drop therefrom into the magazine entrance C, from which in turn they pass into the magazine D. The matrices are of the customary form and are provided with the projecting ears X, which engage in the side grooves G, formed in the magazine and having the widened or flared mouths H. As previously stated, the bodies of the matrices vary in size from very thin to very thick, but their ears X do not vary nearly to the same extent, and they are therefore all adapted to engage and travel in the grooves G, without regard to their body dimensions.

In order that the matrices may be properly directed into the magazine, I provide the entrance with means to engage and guide the matrix ears, which means are preferably in the form of grooves E having widened or flared months F to insure the reception of the ears therein. The groves E extend entirely through the entrance C and register with the corresponding grooves G of the magazine, in such manner as to constitute substantially continuous tracks or ways. It will be seen that in this way the ears of the matrices are always controlled and guided, from the time the matrices leave the distributing mechanism until they are seated in the magazine, and this irrespective of their body thickness; and further that it will be no longer necessary to alter the relative width of the entrance channels for different fonts or to bend the partitions, or to depend on the width of such channels for the purpose of guiding the matrices into the magazines. Further, it will be apparent that my improved devices are equally applicable to magazines and entrances provided with partitions to form channels therein, or where the partitions are entirely omitted, as the said guiding devices may be relied on exclusively. to secure the proper separtion of the type or matrices.

Although I have illustrated and described my invention in preferred form and by way of example, it will be obvious that other v equivalent ordiiferently-located guides may be similarly employed, the essential object of my invention being to effect the proper direction of the type or matrices into the magazine irrespective of their style or thickness, and to deliver such type or matrices thereto in the same relation in which they are received from the distributing mechanism.

Many modifications of my invention will suggest themselves to those skilled in the art, and still be comprised within its scope.

Having thus described my invention, its construction and mode of operation, what I claim and desire to secure by Letters Patent of the United States, is as follows:

1. In a typographical machine, comprising type or matrices formed with projecting ears, the combination of a channeled magazine to contain the type or matrices, and a separate entrance to cooperate directly with the magazine, the said entrance being formed with a series of sets of grooves, one set for each channel of the magazine, to engage the ears of the type or matrices and guide them in their passage through the entrance into the magazine.

2. In a typographical machine, comprising type or matrices formed with projecting ears, the combination of a channeled magazine to contain the type or matrices, and a separate entrance to cooperate directly with the magazine, the said entrance being formed with a series of sets of grooves extending substantially therethrough, one set for each channel of the magazine, and wherein the ears of the type or matrices travel in their passage through the entrance into the magazine.

3. In a typographical machine, comprising type or matrices formed with projecting ears, the combination of a magazine having a series of channels for the type or matrices, and a separate entrance to cooperate di rectly with the magazine and having a corresponding series of channels, the said entrance channels being constituted solely by opposing grooves formed in the side plates of the entrance and wherein the ears of the type or matrices travel during their passage through the entrance into the magazine.

4. In a typographical machine, the combination of a magazine formed with a series of grooves for the type or matrices, and a separate entrance to cooperate directly with the magazine, and formed with a corresponding series of grooves; whereby the type or matrices will be guided wholly by their ears in their passage through said parts.

5. In a typographical machine, the combination of a magazine, and a separate entrance to cooperate directly therewith, each of said parts being formed with a series of grooves corresponding to that of the other to engage and guide the matrices by their ears, and the grooves of each part being beveled or flared at their upper ends to facilitate the guiding of the type or matrices.

In testimony whereof I have afiixed my signature in presence of two witnesses.
